WINDOW-VENTILATOR.

Specification of Letters Patent.

Application filed December 4, 1912. Serial No. 734,997.

Aful Window-Ventilator, of lwhich the following is the specification.

My invention has for its object the construction of a ventilator adaptedfor application to a window, and which can be readily placed in positionor removed therefrom, andby means of which air may be admitted inregulated volume and free from drafts to the dwelling, car, or otherstructure to the windows of which my device is applied. v

A lfurther object of my invention is the construction of a device ofthis kind equipped with means whereby the air passing therethrough isfreed from dust or other foreign substances.

With these and other objects in View my invention consists in certainconstructions, combinations and arrangements of parts, the preferredembodiment ofwhich willnbe hereinafter fully described in connectionwith theaccompanying drawing'and pointed out in the claims.

In the accompanying drawing wherein like parts are designated by thesame reference numerals wherever they occur, Figure 1 is a perspectiveview of theinsideof a window-frame' and sash and showing-my improvedventilator applied thereto; Fig. 2

Vis a partly broken view of the defiectlng` member forming the frontof'my device and showing a screen-framepivoted Aon the inner sidethereof, and Fig.3 is a central cross sectional view.

L1 designates a lwindow-framed@ a window-sash and 7 a window-sill, aliof the usual construction. The sash is shown as raised a sufficientdistance to provide a space in which my improved ventilator is placed.

8 designates a' partition board ,adapted to be inserted under a raisedwindow, and which is provided at itslower and upper edges with strips 9.Between' the 'ends of the strips v9 is an opening 10, and which iscovered at the rear by a downwardly-depending hood ll'attached to theouter side of the plate 8. Secured to the lowerstrip 9 and' extendinginwardly therefrom isa bottom board l2, of a length equal tothe opening10, and extending beneath said board and secured to the inner face ofsaid 4lower strip 9 is a filler piece 13, of a width adapted to rest onthe top of the windowsill 7, when the device is in place.

To the plate 8, at each end of the openin 10 therein, are secured endpieces 14, pre erably having their front edges inclined as shown.Pivoted between the said end pieces 14 is a swinging detlecting member15 pivotally connected with lthe end-pieces 14 bypivots 16, and carryinon its rear face 1a screen-frame 17 hinge thereto by suitable hinges 18.A hook 19 is provided, whereby the said screen-frame may be securedagainst the inner face of the delecting member 15 or permitted to tilttherefrom, with its upper edge resting against the upper strip 9. L

20 designates a rack-bar connected at its rear end to theupper strip 9of the plate 8, its front end passing through an opening in the ear 21on the upper edge of the deflecting member 15, with the teeth on the.

rack-bar enga ng such opening, whereby the angle of t e deflectingmember can be adjusted to regulate the quantity of air Patented Nov. 11,1913.

passing through the ventilator. Extending l across the rear of theopening 10 is a wirescreen 22 which, in connection with the screen 17pivoted on the rear ofthe deiecting member 15, serves to effectivelyscreen all dust or other foreign matter from the air passing through theventilator. When the device is placed in a window the deflectying member15 is tilted outwardly the desired distance and secured at such angle bythe rack-bar 20. The screen-frame 17 on the rear of the detlectingmember 15 is permitted to swing rearwardly against the faoe of the upperstrip 9. Air willnow pass under the hood 11 and through the screensections 22 and 17 and be deflected upwardly into the room by thedeiiecting member 15, thereby preventing all direct draft.

As' will be seen my device is simple in Aconstruction and inexpensive incost of construction, and will eifectively serve the purpose for whichit is designed.`

I am aware that considerable variation is possible in the details ofconstruction herein shown and described, without departing from thespirit of myinvention, and I do not intend to limit myself thereto,except as pointed out in the following claims, in which it is myintention to claim all the novelty inherent in the structure shown anddescribed as broadly as the state of the art will permit.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is:

1. A Ventilating device, comprising a partition board having an openingtherethrough and adapted to be inserted beneath a Window sash, a hoodattached to the rear of said board, a screen section covering the rearof said opening, members secured to the front of said board and iiankingthe opening therein, a def'lecting member pivot-ally connected betweensaid members, and a screen member hingedly connected to the rear of saiddeiecting member.

2. A Ventilating device, comprising a partit-ion board having an openingtherethrough and adapted to be inserted beneath a Window sash, a hoodattached to the rear of said board, a screen section covering the rearof said opening, members secured to the front of said board and flankingthe opening therein, a delecting member pivotally connected between saidmembers, a screen member hingediy connected to the rear of saiddefiectinfr member, and means connecting said deecting member With saidboard whereby the defieoting member may be adjusted at varying anglesthereto, for the purpose set forth.
